[SOLVED] P2642 Code: How To Fix Torque Management Feedback Signal Issue

The P2642 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light. This fault code is caused by a faulty Engine Control Module (ECM), Transmission Control Module (TCM), or poor electrical connection in the ECM circuit.

The importance of repairing this issue lies in the fact that it can lead to further damage to the vehicle’s engine and transmission. The repair difficulty is moderate, with a repair time of 1.0. To fix this issue, one must visually inspect the related wiring harness and connectors and check for damaged components.

It is essential to interpret the fault code correctly to ensure the proper repair of the vehicle.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of p2642 fault code. Here are the symptoms to look out for:

  • The P2642 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, or difficulty starting the engine.
  • The vehicle may also experience poor acceleration or reduced fuel efficiency.
  • Additionally, the driver may notice a decrease in overall performance or a lack of response from the throttle.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2642 can be caused by various factors, including faulty modules and poor electrical connections.

  • The automobile fault code P2642 can be caused by a faulty Engine Control Module (ECM).
  • It can also be caused by a faulty Transmission Control Module (TCM).
  • Another cause of this fault code is an outdated Engine Control Module (ECM) software or Transmission Control Module (TCM) software.
  • An open or shorted Engine Control Module (ECM) harness can also cause this fault code.
  • Lastly, a poor electrical connection in the Engine Control Module (ECM) circuit can also be a cause of the P2642 fault code.

To fix the p2642 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2642, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2642 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P2642 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2642 fault code is related to the transmission control module (TCM) and engine control module (ECM) communication. The TCM may request the ECM to reduce engine torque during shift events to improve shift feel.

If the ECM is unable to comply with the request, it sends a torque reduction failure message to the TCM. The P2642 code is set when the TCM receives this message from the ECM.

This fault code is related to the Torque Management Feedback Signal ‘B’ RangePerformance. A fault in the CAN communication network will not cause this code to set.

What are the possible causes of the automobile fault code P2642?

If you see the engine light on or service engine soon warning light, it could be due to the P2642 fault code. This code can be caused by a faulty Engine Control Module (ECM), Transmission Control Module (TCM), or poor electrical connection in the ECM circuit. It can also be caused by outdated software in the ECM or TCM. To fix this issue, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
